RIFLEMANS SCORE-SHEET.

Specicaton of Letters Patent.

Patented April 6, 1909.

Application filed September 2, 1908. Serial No. 451,336.

To all whom it may concern:

i l l l ln the lower portion of the sheet is a space,

Be it known that l, EDWARD NEELE JOHN- B, arranged for keeping a record of the score sTON, an otlicer oi the U. S. Army, and a citizen of the United States, have invented certain new and useful improvements in Rifleniens Score-Sheets, oi which the following is a specilication, due reference being had to the drawing accompanying, which l mean shall be considered as a part of the saine.

My invention relates to an improvement in score-sheets ot the kind used by riiieinen in keeping a systematic record of the results of their shooting in target-practice, with a record of the various conditions aiiiecting the shooting, such as wind, light, temperature, etc., and a record or" the setting of the riliesight during the shooting. To assist the riiieman in keeping records as indicated above, various types of score -sheets have been inade for use of the members of the United States Army and other riiiemen these sheets are used singly or bound together in some convenient forni.

Whe-never during rifle-shooting there is any wind blowing from any direction except either straight from the target or straight away from it, it is necessary for the rilenian to ascertain what lateral deiiection of the rifle-sight should be used to compensate for the action oi the wind in making the bullet deviate either to the right or to the lett from a straight course toward the target.

lt is the purpose of the present invention to provide a means whereby the riileman can ascertain at a glance the proper lateral windage correction to use when shooting in a wind ol" a given direction and velocity, and to place this windage device in a convenient place on the riilenians score-sheet itself, where it is constantly visible to the rifleman during his shooting. The means whereby l attain said purposes will be evident from the description which l shall now proceed to give, and from the accompanying drawing.

Figure l is a plan view oi trie entire scoresheet, showing the windage-device in combination with the ordinary features of rileinens score-sheets. Fig. 2 is a detail plan of the windage device alone.

ln Fig. l in the upper left-hand corner of the score-sheet is a representation of a rectangular target intended to be used in plotting the location of hits on the target and for indicating the changes of sight-settings required in order that subsequent shots may hit the target.

and the setting ot the sight for the different shots tired. ln the lower right-hand corner of the sheet-is a space, C, intended to be used for any notes for which space is not provided elsewhere on the sheet. Just above the space C, is a space D, arranged for keeping a record oi the time, weather conditions, etc.

ln the upper right hand corner oll the sheet is the windage device, E. lt will be observed that this device contains a series ol' concentric circles and that at points where these circles are intersected by imaginary lines trom the center toward the hour points ol a clocki'ace are various numbers. lt is customary for rifiemen to express the direction oi the wind by a clock-tace notation, the clock-tace being supposed to be held in the hand with the hour XH toward the target and the hour lll at the right-hand. A wind blowing directly from the target is tiled Xll oclock wind: one blowing `from the leit a lX oclock wind, etc. The rear sight oil a rii'le is gener'- ally so arranged as to permit oil a lateral movement ol' the sight to compensate i'or the deviating tendency of the wind. The ritiesights are generally graduated in points 'for this lateral movement by lines spaced at equal distances apart. ln the windagedevice herein described the numbers in the line VldXll. represent the velocity ol the wind in miles per hour. The numbers on any one circle represent the lateral correction in points and :fractions oi points ol' the wind-gage required to ccmpcnsate for the deviating components of winds having the velocity marked on that particu circle where it crosses the line Vl-XlL and having vthe particular direction which corresponds to the radiating line on which the windage correction is l'ound. it is to be particularly observed that the windage corrections l'or winds blowing l'i'oin anydirection ol' the clock are to be i'ound in a corresponding direction on the windage indicator. This greatly facilitates the determination oil the proper correction.

The following will serve to illustrate the use ol' the windage-device: Before a rilieinan commences to 'lire at any range he ascertains the velocity oi' the wind Vfrom an aneinoineter and its direction. troni a clockiace indicator on the target range or else ne estimates the velocity and direction by observing the movements ol trees, ila-gs, etc.

Suppose that he is going to i'ire at the 600 yard range and that he linds the velocity of the wind to be 2O miles per hour and that its direction is from 111 oclock. A glance at the windage-device on his score-sheet shows him instantly that he should use a lateral correction ol' 3 points. Suppose, new, that after he has fired a i'ew shots the wind decreases in velocity to 16 miles per hour; another glance tells him that he should decrease the lateral correction to 2 2/5 points. Suppose, now, that the wind changes in direction id blows from V oclock. 'llie windage device tells the rifleman at once that he should decrease the dellection to 1 1/5 points. As the windage device isV constantly in Vfront ol the riiieman during all oil his iiring he is enabled to ascertain instantly whether a certain change in the wind velocity or direction is enough to call lor any change in the sight-setting and the amount of the change required.

VV hile the invention has been described as an improvement in rifiemens score-sheets it is to be understood that the windage device may be used also on score-cards or independently merely as an aid to the proper adjustment of the sight.

The device has been shown in the iigure as arranged for 'liring at the 600 yard range, but it is to be understood that the same device is intended for use at all the other ranges at which firing is held, the sole difference being in the numbers representing the windage corrections.

I do not wish to be understood as limiting myself to the particular number of velocity circles shown in the iigures, nor to the particular numbers shown either as representing the velocity ol the wind or as representing the windage corrections.

While the drawing shows a particular arrangement on the score sheet of the dit ferent component parts specifically de scribed herein, 1 do not wish to be understood as limiting my invention to the particular arrangement of parts shown and described, it being well understood that the various component parts may be otherwise placed on the score sheet.

TvVhile the drawing shows the windage device as a collection of complete and concentric circles, etc., it is to be understood that the same information which -is obtainable from the windage device as shown and described may be obtained, though not so conveniently, from a portion of the device containing parts only of the circles, the corrections for 1, V, V11, X1 oclock, 11, 1V, V111, X oclock, and 111, 1X oclock being numerically the same, and it is to be understood that such an arrangement is conteniplated for use in cases where it is essential or advisable to economize space on the score sheet.

circles or parts of circles mentioned herein and shown in the drawing are of great assistance in quickly ascertaining the 'windage correction corresponding to a particular velocity of the wind, a series of lines forming either chords or arcs of circles may be used, or the circles may be entirely imaginary, all corrections corresponding to a particular velocity of the wind, being arranged approximately on the circumference oiC an imaginary circle.

1 wish it also to be understood that although the windage device is shown in the drawing in combination with a representa tion of a rectangulartarget, such as is used during what is called slow iireH in target practice, the device may also be used in combination with a representation of any kind of target at which tiring is held on a target range, and such a combination is contemplated herein.
